Improvement in sash-fastener



4 t hereby dee-lare that 'the follo A DANIEL ARMSTRONG, or CHICAGO, ILLINoie.

Letters Patent No. 83,439, dated Octobw- 27, 1868.

The Schedule referred to in these Letters Patent Vand making part of the same.

To all whom. it may concern Be it known that I, 'DANIEL Anns'rnoxo, of Ohieago, in the county ot' Cook, in the State of Illinois, have invented an Improved Sash-hastener; and I do ing is a i'ull and exa-et description thereof', reference being,l had to the aecompanying drawings, and to the letters ofreterenee marked thereon, making a part of this specification, in which- Figure l is alongitudinal elevation oi' my invention, as4 applied to a sash. l

his invention relates to an improvementon that class of fasteners which are placed parallel with the ylower Iail of the sash, and have a doubley bolt with rubber in its ends, for holding the sash in position; and its nature, in part, consists in the use ot' acentral thimhle or socket, which supports the inner ends ot' tubular bolts, and also a eoil-spring. The latter passing into the ends ofthe bolts, is made to operate both oi' them at the same time, and hold the sash in plaee.

To enable othersskilledin the art to make and use my invention, I have niarked col'responding parts with similar letters, and will now give a detailed description.

H represents the lower rail of asash, andi. the. frame in which it runs. The bolts ofthe. fastener, shown at A A', are made of i'netal pipe, oi'suitable size and strength, and have metal heads or partitions, la 71, rigidly attached to` their inner sides, and at suitable distances from the ends, to permit rubber plugs, F l1, to

be inserted. in the usual manner.

And pins d d are put through lthe bolts, at suitable distances from their inner ends, and used as supports for a mil-spring, m, to bear against. This eonstruetimi will lmelearly seen by reti-renee to the sectional drawing oi' bolt A.

,l5 represents a metal thii'nble, which is made large enough tor the inner ends ot' the bolts to slide in', and it has lugs at the bottoni and top, through whieh screws c c c are put, to hold it to the sash, the upper lug terniinatingin a lifter, E, for raising the sash in the usualmanner. The outer ends of the. bolts are held in position by means ot' thimbles G G, made large enough for the bolts to slidtl in, andare fastened to the sash nl the. same inan11er.'is the thilnble B, Thumb-pieces C C are attached to the bolts A A', at suoli distances from their inner ends as is convenient for graspingr them by the thumb and linger, and lowing the bolts from the sash-frame- I I know that the apljllieation oi a double bolt lor iastening sash is not new, neither is the. rubber F in the end. I thereiine limit the scope of 1u y impro vement to the peculiar eonstruetion oi the bolts`l and the novel ina-nner in which they are operate-Quot claiming to have originati-d an entirely new iii-steuer. The dilel'` ence, however, between this devicel and others used tor a like purpose, is very obvious, ina-Smueh as the bolts A A are hollow, with a single spring,r inside, and eon` sequeutly require no easing to conceal any of the working parts'. And as to eheapness, inv fastener eau be made at less than one-halt' ot' the eosl; ni similar iuventions, which are as durable and comunioni'.

Having' thus described my inventhni.

Whatfl. claim, and desire to seoure by Letters Patent ot' the United States, is*

The. arrangement of the thii'nble l and eoilsspringr m, the. latter fitting into the ends of the bolts A A',

and operatingr both o1" them at the same time, in coinbination with thhnbles G G, pins (Z cl, and thumb-pieces e e, as and for the purpose set forth.'
